“Lots of subjects discussed regarding their platform, and the world of social media in general,” Trump wrote. “Look forward to keeping an open dialogue!”

In a statement, a Twitter spokesperson said, “Jack had a constructive meeting with the President of the United States today at the president’s invitation. They discussed Twitter’s commitment to protecting the health of the public conversation ahead of the 2020 U.S. elections and efforts underway to respond to the opioid crisis.”

Among others in the room, Trump was accompanied by Dan Scavino, the White House director of social media and a longtime Trump aide who frequently posts for him on Twitter. Dorsey was accompanied by Vijaya Gadde, Twitter’s head of legal, policy, and trust & safety.

For years prominent Republicans and right-wing media personalities have repeatedly made unfounded accusations that Twitter and other social media platforms are biased against conservative users.

Trump has amped up such accusations since he took office.

Earlier on Tuesday, for instance, Trump tweeted that Twitter is “very discriminatory” and does not “treat me well as a Republican.” The President said it was “hard for people to sign on” and accused the company of “constantly taking people off list.”

“No wonder Congress wants to get involved – and they should,” Trump added in a tweet. “Must be more, and fairer, companies to get out the WORD!”

Trump’s meeting with Dorsey also came a month after Gadde told The Washington Post that Twitter was considering labeling tweets which violate its rules, but which the company permits to remain online because they are deemed to be in the public interest.

Such a move could potentially impact Trump, as some critics have suggested his tweets have violated the platform’s terms of service.
